What is Telnet?

Telnet is a contraction of two words of the telecommunications network and is one of the main network protocols used on the Internet. It is one of the earliest network protocols and one of the only original protocols that are still commonly used on the Internet. It was developed in 1969 with RFC 15 and has evolved as a robust protocol over the years, although concerns about security security often apply instead of secured SSH protocol. The original purpose of Telnet was to have an easy interface for terminals for interaction with relatively simple command structures and accessible interfaces. Although still used, Telnet is rarely used by most of the public passing through the Internet, which instead uses http and clients by e-mail.

At the age of personal computers, anyone who wanted to use a computer generally had to approach a terminal that was associated with a massive mainframe. Originally each terminal was connected to only one machine, which led tomany problems. For example, if one person needed to use a number of different machines, each specializing in a different task, it would have to physically go to any other terminal to do one job. This could be frustrating if the terminals were placed in a large building, but especially crazy about the mainframe you needed to use, was placed in an institution in another city or country from you.

Telnet protocol helped overcome this difficulty. Using a simple set of commands, users could log in to a remote terminal and ask the mainframe to do any processes they needed. The results would return to them via Telnet and it was like Tyh sitting in front of the terminal itself. In many ways, the Telnet helped the Research on how research was done and helped build what would eventually become the Internet that we know today.

Of course, not all early uses for Telnet were so practical. Actually has one of the ways of tElnet still used to this day, roots in 1978, when a student at Essex University built on the earlier success of terminal games, such as Adventure and zork This virtual environment, which includes other varieties such as mushrooms and MoOS. Once they are there, they can play a collective game, often thematic imagination, text commands and reading answers and inputs from other players. Although the use of mud has reduced the advent of graphics massively multiplayer online playing roles (MMORPG), they remain the main use of TPROKOK Telnet with hundreds of thousands of players around the world.

Although at one point Telnet was used at one point as a network of network administrators and those who needed to deal with their servers is rarely used for this purpose. In 1995, a research worker at the University of Helsinki in Finland, harassed the security holes in Telnet that allowed a sniffThe attacks and attacks for malicious slogans, built a new protocol that replaced it. This protocol, Secure Shell or SSH, has most of the same Telnet properties, but has much more robust security.
